wx.propgrid.BoolProperty sub-properties are created for editing individual bits. Textctrl is created to manually edit the flags as a text; a continuous sequence of spaces, commas and semicolons is considered as a flag id separator. Note: When changing “choices” (ie. flag labels) of wx.propgrid.FlagsProperty, you will need to use SetPropertyChoices - otherwise they will not get updated properly.

Must return new value of the whole property (after any alterations warranted by child’s new value).

Note that this function is usually called at the time that value of this property, or given child property, is still pending for change, and as such, result of GetValue or m_value should not be relied on.

Sample pseudo-code implementation:

# TBW

Parameters:

thisValue (PGVariant) – Value of this property. Changed value should be returned (in previous versions of wx.propgrid.PropertyGrid it was only necessary to write value back to this argument).

childIndex (int) – Index of child changed (you can use Item(childIndex) to get child property).

argFlags (int) – If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable value instead of displayable one (they may be different). If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, text is interpreted as a part of composite property string value (as generated by ValueToString called with this same flag).

Return type:

tuple

You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).

Returns:

( bool, variant )

Note

Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.

argFlags (int) – If 0 (default value), then displayed string is returned. If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable string value instead of displayable. If wx.propgrid.PG_EDITABLE_VALUE is set, returns string value that must be editable in textctrl. If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, returns text that is appropriate to display as a part of string property’s composite text representation.
